After over a year away from the K-pop scene, Girls’ Generation are back. The nine gorgeous idols marked their return to the music scene today with the video for new single, “Mr.Mr” — taken from their hotly anticipated fourth mini album of the same name.

In the brightly-colored four-minute video, the girls operate on a handsome model who has stolen their hearts, while showing off impressive dance moves in sexy and sophisticated outfits.

The hospital scenes surrounding their dance breaks stick to the upscale theme of the previously release teasers. Tiffany, Jessica, Sooyoung and the other members portray sexy doctors and nurses in sexy curve-hugging outfits.

They bring their handsome mister to a neon colored hospital room filled with an array of jeweled hearts and other sparkly organs to transplant.

The single’s message is about urging a dream man to open up his heart. They group sings about how hard a girl can fall a particular mister and they want him to be equally as bold about his feelings.

Despite the Underdogs-produced single suffering delays due to the dates files from the video shoot getting corrupted, “Mr.Mr” has still managed to hit number one on nine of Korea’s music charts, including MelOn, Olleh Music, Naver and Daum Music.

On March 6, the idols will debut their new hit song on Mnet’s M! Countdown stage.
